Manuscript AI vs ProWritingAid

Prices checked · By Prannay Kedia, founder of Manuscript AI

We make Manuscript AI, one of the options compared here, so we've tried to say plainly when another is the better choice. Every figure about another provider links to its source.

The short answer

ProWritingAid is a writing and line-editing toolkit that works inside Word, Google Docs and Scrivener; Manuscript AI is a one-off $19 structural report on a non-fiction manuscript. ProWritingAid's whole-book analyses cost one Story Credit each ($25–$50) on top of any plan, and ProWritingAid says they give the most value on fiction. Choose ProWritingAid to polish sentences as you write; choose Manuscript AI to check whether a non-fiction draft's structure and argument hold up.

Why authors choose Manuscript AI

Polish comes last. Structure comes first.

  • Built for non-fiction

    Every question in the report is about a non-fiction book: whether the argument holds, whether chapters build on each other, whether readers know what to do next. ProWritingAid says its Manuscript Analysis gives the most value on fiction.[1]

  • The whole book, not the next sentence

    Line-editing reports work sentence by sentence. The report reads every chapter together, so it can flag a chapter that repeats another or an argument that drifts.

  • $19 once, no plan

    No subscription and no credits. ProWritingAid's whole-book analyses cost one Story Credit each, $25–$50, on top of any plan.[2][3]

After three beta readers, four different types of editing software and a costly developmental edit, your report had new, actionable information on each chapter.”

From a real report

“Chapter VIII on movement is the clearest rupture. After the narrative warmth of Ogimi and the diet chapter, it becomes a catalogue of yoga types, tai chi styles, qigong’s ‘Tyau Shenn’ and step-by-step postures, and the Six Healing Sounds. The tie to ikigai is thin, and the chapter’s own admission, ‘It might feel confusing to be presented with all the Eastern traditions,’ confirms the overload.”

“Improvement: Open each chapter with a one-sentence bridge stating its link to ikigai…”

Who it's for

ProWritingAid is built for writing and revising at the sentence level: grammar, style, overused words, sticky sentences and readability, across every project you work on.[2]

Manuscript AI is for a different moment: the non-fiction draft is finished and you want to know whether its structure, argument and chapters work as a whole.

Price

ProWritingAid's free plan checks 500 words at a time. Premium costs $30 a month, $120 a year or $399 for life; Premium Pro costs $36 a month, $144 a year or $699 for life. Yearly and lifetime plans have a 3-day money-back guarantee; monthly plans aren't refundable.[2]

The whole-book reports (Manuscript Analysis, Plot Analysis, Virtual Beta Reader and Marketability Analysis) aren't included in either plan. Each run costs one Story Credit: $50 without a plan, $35 with Premium or $25 with Premium Pro. New accounts get one credit to try.[3][5]

These are US prices. ProWritingAid shows local prices in some countries and runs periodic sales.[2]

Non-fiction fit

“You may find the most value when using it for fiction.”
ProWritingAid[1]

ProWritingAid's line editing works on any kind of writing, and it says Chapter Critique "can be used on any genre of book, including memoir and nonfiction."[6]

Its whole-book Manuscript Analysis looks for story elements such as plot holes, characters and world-building, and ProWritingAid's own FAQ says it gives the most value on fiction.[1]

Manuscript AI: Built only for non-fiction: self-help, business, memoir, biography and research-based books. It doesn't analyze fiction.

Using both

They do different jobs, and many authors use both: Manuscript AI to check the book's structure and argument once the draft is complete, then ProWritingAid to tidy the sentences in the chapters you rewrite.
